Your meeting room has a strong Wi-Fi signal, yet calls stutter when neighbouring rooms fill up. Before upgrading the internet plan, compare a wired call with a Wi-Fi call and check what nearby access points share the same radio spectrum.
Check whether the slowdown follows the room
Use the same laptop and call application on Wi-Fi and a wired connection during the period when staff see the problem. Record the room, time, connected access point and band. Check latency, packet loss and call quality. If the wired result is poor too, investigate the upstream network and service before changing Wi-Fi. If the slowdown affects people walking between rooms, use the separate office Wi-Fi roaming guide.
Review channel width alongside interference
Wider channels can provide higher throughput in clean spectrum, but they occupy more of it. In a dense office, several access points and neighbours can end up sharing overlapping spectrum. Ubiquiti’s UniFi WiFi troubleshooting guide explains how to review channel use, interference and airtime. Check the environment around each affected access point and compare busy-hour trends. High utilisation can come from your own traffic as well as neighbours.
Test whether a narrower channel on the affected band lets you use cleaner, distinct channels in adjacent rooms. Record existing settings first and use a change window. Let the controller enforce the configured country and device restrictions. If considering channels with radar detection requirements, check device support and account for possible channel changes. Keep wireless uplinks and neighbouring access points in the plan so a change does not simply move the problem.
Measure the work staff need to do
Compare two calls in neighbouring rooms before and after the pilot, then try a typical file transfer. Check whether call quality improved at the busiest time and whether throughput still meets staff needs. Use the same devices and locations. Document the setting that worked and revert if the pilot makes coverage or reliability worse. The guide to office network configuration recovery can help with rollback planning.
